Why Kodi Buffers
Buffering happens when video data isn’t downloaded fast enough to stay ahead of playback.
Kodi is more sensitive than apps like Netflix because:
- It relies on third-party streaming sources
- It uses local device RAM heavily
- Many devices (especially Firesticks) have limited resources
If you’re seeing similar issues outside Kodi, our guide on fixing streaming lag and buffering on Fire TV devices explains why this happens across apps.
Buffering doesn’t always mean slow internet — it often means poor optimisation.
Common Causes of Kodi Buffering & Freezing
Kodi buffering usually comes down to one or more of the following:
- Weak or unstable internet connection
- Overloaded or low-quality streaming sources
- Incorrect Kodi cache configuration
- Hardware acceleration conflicts
- Heavy builds on low-RAM devices
- ISP throttling streaming traffic
Before changing advanced settings, it’s worth checking the basics – including your network setup. If you’re using a Firestick, see our guide on clearing cache and improving Fire TV performance.
Recommended Internet Speeds for Kodi
These figures are still accurate and realistic in 2026:
- SD (480p): 2.5 Mbps
- HD (720p): 5 Mbps
- Full HD (1080p): 10 Mbps
- 4K (2160p): 25 Mbps
These speeds are per device. Two Firesticks streaming 4K need ~50 Mbps consistently.
You can test your real-world speed using fast.com. For deeper network optimisation, see our Wi-Fi setup guide for 4K streaming devices, which covers router placement, interference, and real-world fixes.
How to Fix Kodi Buffering & Freezing (Step-by-Step)
Below are the most effective ways to fix Kodi buffering and freezing on Firesticks, Android TV, and more powerful streaming devices.a
If you’re setting Kodi up from scratch, follow our step-by-step Kodi installation guide for Fire TV before applying these fixes.
Step 1: Clear Kodi Cache (Fastest Win)
This alone fixes buffering for many users.
- Settings → Applications → Manage Installed Apps
- Kodi → Clear cache
Clear data unless you want to reset Kodi.
If performance issues persist across apps, a full Fire TV or Google TV reset can sometimes resolve deeper system-level slowdowns.
Step 2: Optimise Kodi Cache Settings (Most Important Step)
Kodi allows manual cache tuning using an advancedsettings.xml file.
The easiest method is The Crew Wizard, which still works reliably in 2026. The following steps will show you how.
The following steps involve using a community-made wizard to automate technical settings. While tools like The Crew Wizard are widely used to fix performance, they are third-party add-ons. We recommend using a reliable VPN like NordVPN to ensure your connection remains private and to prevent ISP throttling during the setup process.
Enable Unknown Sources
- Open Kodi, then select Settings (cog icon)
- Select System
- Tap down the menu on the left to highlight Add-ons
- Tap to the right, then select Unknown sources to turn this setting on
- Read the warning, then select Yes
- Press the back button on your remote to return to the System menu
Install The Crew Repository
- Open the Kodi Settings
- Select File Manager
- Then select Add source
- Select the box labelled < None >
- Next, enter the following URL exactly as you see it: https://team-crew.github.io
- Select OK
If you cannot find the colon key : select the CAPS LOCK button
- Tap down, then select Enter a name for this media source
- Enter crew or any other name you’d prefer to use instead to identify this media source
- Then select OK
- Press the back button on your remote several times until you are back at the System menu
- Select Add-ons
- Select Install from zip file, then select Yes if you see a warning message
- Tap down, then select crew (or any other name you used to identify this media source)
- Next, select the zip file repository.thecrew-x.x.x.zip
- Select OK
- Wait until a confirmation message appears in the top-right corner of the screen that the installation is complete
Install The Crew Wizard
- Press the back button on your remote several times until you are back at the System menu
- Select Add-ons
- Next, select Install from repository
- Select The Crew Repo
- Then, choose Program add-ons
- Next, select The Crew Wizard
- Choose Install
You’ll see a confirmation message in the screen’s top-right corner that The Crew Wizard addon is installed. A message will appear on the screen after a few moments. Read then dismiss the message.
- Select Continue
- Then, select Ignore
- Select The Crew Wizard
- Then, select Open
- Select Maintenance
- Then, select System Tweaks/Fixes
- Select Advanced Settings
- Next choose Quick Configure AdvancedSettings.xml
- Accept all of the recommended changes and select Write File
- If you already have an AdvancedSettings.xml file, it will ask you if you want to overwrite it. Select Remove Settings to continue
Over-sized cache values can cause crashes on Firesticks — always use recommended settings.
Step 3: Delete Kodi Temporary Files
Temporary files slow Kodi over time. Use The Crew Wizard to delete them.
- Open Kodi and select Add-ons
- Then, select Program add-ons
- Select The Crew Wizard
- Select Maintenance
- Then, select Cleaning Tools
- Next, choose Total Clean Up
- Finally, choose Clean All
Do this monthly.
Step 4: Turn OFF Hardware Acceleration
Hardware acceleration causes stuttering on many Fire TV devices. However, you can fine-tune system-level performance using our recommended Firestick 4K HDR settings, especially on older or entry-level models.
One of the biggest causes of Kodi buffering issues is hardware acceleration. You might be able to resolve all of your problems by just disabling it.
- Open Kodi, then select Settings (cog icon)
- Select Player
- Select the cog icon in the bottom left several times until the wording changes from Basic to Expert
- Select Videos from the menu on the left
- Then, tap over to the right and disable all hardware acceleration options
- Restart Kodi
Step 5: Reduce or Disable Video Scaling
Kodi upscales low-quality streams, which strains weaker devices.
- Open Kodi, then select Settings (cog icon)
- Select Player
- Select the cog icon in the bottom left several times until the wording changes from Basic to Expert
- Select Videos from the menu on the left
- Then, tap over to the right and reduce Enable HQ scalers for scaling above to 10%
- Test the video, if buffering persists, change to 0%
Step 6: Use Real Debrid (Massive Upgrade)
Real Debrid is an unrestricted downloader that allows you to download files instantly and at the best of your internet speed. Despite being a subscription service, Real Debrid remains on of the best ways to eliminate buffering.
Benfits:
- Faster servers
- High-quality links
- Less congestion
- Better 1080p and 4K playback
Create an account at the Real Debrid website, then link your Real Debrid account to your Kodi addon, or build, by following steps by searching for online tutorials.
Even budget Firesticks perform far better with Real Debrid.
Step 7: Use a VPN to Prevent Throttling
Some ISPs still throttle streaming traffic.
A VPN:
- Encrypts your traffic
- Prevents throttling
- Improves stream consistency
- Unlocks geo-restricted content
I personally use NordVPN because it has fast servers, a dedicated Fire TV app, and works reliably with Kodi. If you’re new to this, see our VPN for Firestick & Google TV: Secure Streaming Guide.
Advanced users may prefer a VPN set up directly on the router, which protects all streaming devices automatically.
Practical Tweaks That Make a Big Difference
Even with the correct settings, Kodi performance is heavily influenced by how it’s used day to day, particularly on compact streaming devices.
These aren’t replacements for the fixes above — they explain why Kodi still buffers for some users even after setup.
Use Lightweight Setups on Streaming Sticks
Modern Kodi builds are often designed for PCs or powerful boxes, not Firesticks. More powerful devices handle Kodi far better — especially when you take advantage of advanced NVIDIA Shield features and optimisations.
Install massive all-in-one builds packed with dozens of addons.
Stick to one or two reliable addons you actually use.
This reduces memory presusre and prevents freezing during playback.
Prefer Ethernet Over Wi-Fi Where Possible
Wi-Fi congestion is far more common now than it was a few years ago.
If your device supports it:
- A wired connection is always more stable
- Even a USB-to-Ethernet adapter can help
This is especially noticeable on Firesticks used in busy home networks.
Be Selective With Streaming Sources
Not all buffering is caused by your device.
If a stream buffers repeatedly:
- Back out
- Choose a different source
- Avoid low-bitrate or heavily shared links
No cache tweak can fix a bad stream.
When Hardware Matters
If you’ve tried everything and still see buffering, the device itself may be the bottleneck.
More powerful devices like the NVIDIA Shield TV Pro handle Kodi far better thanks to extra RAM and stronger decoding hardware.
FAQ: How to Fix Kodi Buffering
Kodi buffering is usually caused by overloaded streaming sources, poor cache configuration, hardware acceleration conflicts, or device limitations — not raw internet speed.
